mobi2mobi error Windows 7
Ok, so I've attempted to fix this with all kinds of installs, previous versions, etc, but still can't get my mobi2mobi gui to work. I have a windows 7 PC with Mobi2Mobi_GUI_VB_v9 (previous versions 7 and 5) installed using PERL mobiperl-win-0.0.43 (attempted with 42, 40, etc). Windows 7 all ready has .NET 3.5. I receive the error below whenever I attempt to open an .azw file that I want to modify. Any help would be greatly appreciated. I prefer mobi2mobi to Calibre, so please assist!
